ICD-10 Code F65 – Paraphilias (2026): Diagnosis, Symptoms & Billing Guide
2026 ICD-10-CM Diagnosis Code F65 – Paraphilias
What it is
F65 identifies paraphilias, a group of conditions involving persistent, atypical sexual interests. Use it when the record documents a paraphilic disorder or paraphilic behavior pattern, not a general sexual concern.
Clinical signs
Clinical features vary; refer to documentation. Records may note recurrent, intense sexual urges, fantasies, or behaviors focused on nonstandard objects, situations, or persons, with distress, impairment, or risk to others.
When to use this code
Use F65 when the clinician diagnoses a paraphilia or documents a paraphilic disorder and the note supports that diagnosis. It may appear in psychiatry, behavioral health, or forensic documentation. If the chart only mentions unusual sexual interests without a diagnosis, check documentation.
Do not use for
Do not use F65 for normal sexual variation, relationship problems, or unspecified sexual dysfunction. If the record describes another mental, behavioral, or neurodevelopmental disorder more specifically, code that condition instead.
Coding tip
Code only when the diagnosis is clearly documented and supported by the provider’s assessment.
